Abstract:
We added rare earth and titanium in Al-Mg-Si alloy,and the influence of rare earth and titanium onthe microstructure and properties of Al-Mg-Si conductive material were studied in this paper,with the opticalmicroscope,scanning electron microscope,DSC analysis on the microstructure of alloy,and testing the per-formance. The results show that,RE and Ti both have refining effect on Al-Mg-Si conductive material. Whenthe content of RE is more than 0.3% and the Ti is more than 0.15%,the phase Al Ti,Ce will form in Al-Mg-Si alloy,consuming a large amounts of Ti and Ce,which has an unfavorable effect on the mechanicalproperties and electrical conductivity of the alloy.
